Changing rear end bolt pattern.

You could redrill it or just get a free 7.25 from someone as they are unpopular with the mod crowd. There are 8.75 rears that are 5 on 4 but they are $$$ now.

I have a few 7.25s laying around but lack of sure grip units and highway gears rule them out.

An 8.75 is too expensive and over kill for this car.
